Abstract
In recent years, the focus on sustainability and the environment has led to a considerable
improvement of fertilisation techniques applied in the vineyard. Modern viticulture must in fact respond to the new lines dictated by the European Grean Deal, which impose the use of agronomic practices that can best reconcile food production and environmental protection. In light of this, numerous efforts have been made to identify strategies and solutions for the vine nutrition that can meet the objectives of quality and yield objectives, but above all with a view to operating a fertilisation with a low environmental impact, attentive to natural resources and, in
in particular, the soil. The availability of new fertilisers with high nutrient efficiency combined with more modern techniques, based on the knowledge of the timing of needs and absorption of nutrients by the vine, now makes it possible to operate 'precision' fertilisation, avoiding unnecessary waste. The use of these techniques becomes fundamental especially in difficult environmental contexts (e.g. low fertility soils, soils subject to leaching, erosion, etc.) and in years with particularly dry or rainy weather conditions. or rainy years, where the efficiency of fertilisation interventions may be reduced. fertilisation interventions may be reduced.
